Have to perform OS inplace upgrade from windows 2016 to 2019 or windows 2022 which is hosted in Oracle cloud

To perform an in-place upgrade from Windows Server 2016 to either Windows Server 2019 or Windows Server 2022, you can follow these general guidelines:

1. Upgrade Path: You can upgrade directly from Windows Server 2016 to Windows Server 2019 or Windows Server 2022. This is supported for nonclustered systems.
2. Pre-Upgrade Considerations:
   • Ensure that your current system meets the hardware requirements for the new version.
   • Backup your data and settings before proceeding with the upgrade.
   • Check for any application compatibility issues with the new OS version.
3. Upgrade Process:
   • You can initiate the in-place upgrade using the installation media for Windows Server 2019 or 2022. Run the setup and choose the option to upgrade.
   • Follow the prompts to complete the upgrade process.
4. Post-Upgrade: After the upgrade, verify that all applications and services are functioning correctly and that the system is stable.

Keep in mind that in-place upgrades might not be supported by all cloud providers, so you should verify with Oracle Cloud for any specific requirements or limitations they may have regarding in-place upgrades.
